主　　题：Three-Gorges-Dam surface salinity anomalies stratification East China Sea 

摘      要：A fine resolution model has been applied to get more insight into the effects of a modified runoff due to the Three-Gorges-Dam （TGD） on the East China Sea （ECS）.The region of interest was confined to the offshore area in the vicinity of the Changjiang *** the east,it extended up to the area southwest of Cheju *** model was used to evaluate the effect of a modified runoff on the water properties of the adjacent regions like the Changjiang diluted water （CDW） and the Zhoushan Fishing *** sensitivity of the ECS to a modified Changjiang runoff was explored firstly by sensitivity studies and secondly by experiments based on historical runoff records and water management plans of the *** experiments led to the general conclusion that the most affected area by runoff is located close to the Changjiang River *** area of influence has an extension of about 150 km×150 *** the realistic experiment,the related anomalies reached their maximum value in early summer （May）.In normal years the related salinity anomalies can get to as large as 2.
